 Sai Charan said: (Apr 19, 2015) Shape Factor = Plastic Section Modulus/Elastic Section Modulus. Shape Factor = Zp/Zy.

 Abhishek Bhardwaj said: (Jun 2, 2015) zp = A/2*(y1 +y2)y1 = 2d/3pi = y2 pi = 3.14 zy = (pi*d^3)/32 S.F = 1.7.

 Puja said: (Aug 9, 2015) Only for circular. Please mention other too.

 Ganesh said: (Oct 24, 2015) Rectangular = 1.5. Circular = 1.69. Diamond 2. In section 1.15.

 Mandeep Kumar said: (Nov 18, 2015) Diamond = 2. Round = 1.7. Circular = 1.697. Rectangle = 1.5. Tube = 1.27. I-section = 1.14.
